Sorry if this thread has already been posted. First of all I am new so hello everyone. Thank you in advance for any help and advice.
I am running a hydro op under 1000w lights. Vegging for two weeks on a 12-12 and then switching to a flowering formula for the remaining six weeks. Same problem keeps happening though. My plants start getting yellow on the bud hairs. ( the white hairs looked shriveled up and burnt yellow. It is spreading throughout the table. Problem occurs when i switch from veg formula to flower formula in the third week. the plant dries up and dies. the other plants not visually affected have much stunted growth and have lost over half my yeild each time. Is this nutrient burn or a lack of nutrients? I have adjusted my nuts from 1.2-1.4 (flower) to 0.8-1.0 to try and correct it. I am afraid they are going to get worse if i can't resolve quickly. If anyone knows what going on i would love to hear it.
